Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure processing equipment, specifically steel structure prefabricated component processing equipment. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, which are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion and generally require rust removal, galvanizing, or painting, as well as regular maintenance.

[0003] Angle steel is the most widely used material in engineering. It can be assembled into various load-bearing components according to different structural needs, and can also be used as connecting parts between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.

[0004] Welding angle steel requires processing, including beveling at the welding points. Beveling ensures root penetration, facilitates slag removal, and improves weld formation. It also helps regulate the ratio of base metal to filler metal. Currently, beveling still requires manual grinding with a handheld angle grinder. This is slow, labor-intensive, and requires experienced grinders. Inconsistent beveling results in poor weld quality. The actual processing and movement between operations are all manual, leading to long processing times, low overall efficiency, and hindering the need for mass production in factories. Utility Model Content

[0005] To address the problems of high labor intensity, low efficiency, and safety concerns associated with manual grinding of bevels in existing methods, this invention provides a steel structure prefabrication processing equipment.

[0006] This utility model is achieved through the following technical solution:

[0007] A steel structure prefabrication processing equipment includes a workbench with a slide groove. A base is slidably connected and installed in the slide groove. A first motor is connected and installed on the base at an incline. A grinding wheel is driven and installed on the first motor. A bearing seat is also connected and installed on the workbench. A fixing device capable of clamping and fixing angle steel is rotatably connected and installed on the bearing seat.

[0008] A further improvement of this utility model is that the fixing device includes a roller rotatably connected and mounted on a bearing seat. The roller is provided with a positioning block and a partition. The two sides of the partition are a placement groove and an air storage groove, respectively. The partition is provided with a plurality of first through holes. A slider is slidably nested and installed in the first through holes. An air bladder that can be inflated and deflated is provided inside the air storage groove.

[0009] A further improvement of this utility model is that the base includes a guide groove in the direction of the vertical slide groove and a sliding seat for connecting and installing a first motor. The bottom of the sliding seat is provided with a first threaded connecting plate that can slide in the guide groove. The bottom of the guide groove is provided with a through second hole. One end of the second through hole is connected and installed with a second motor. The second motor drives and connects to a first screw that is threadedly connected to the first threaded connecting plate.

[0010] A further improvement of this utility model is that a spiral groove is provided on the surface of the roller, a fixed box is connected and installed on the worktable, a third motor is connected and installed at one end of the fixed box, the third motor drives and connects to a second screw that is rotatably connected inside the fixed box, a second threaded connecting plate that is threadedly connected to the second screw is slidably nested inside the fixed box, and a guide post that slides in the spiral groove is connected and installed on the second threaded connecting plate.

[0011] A further improvement of this utility model is that a connecting block is connected and installed below the base, and a hydraulic rod capable of driving the connecting block to slide is connected and installed at the lower end of the worktable.

[0012] A further improvement of this utility model is that the workbench is equipped with a baffle that can position the angle steel.

[0013] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0014] When using the angle steel, place it into the fixing device, ensuring the angle steel extends beyond the device to the desired bevel length. Keep one side of the angle steel horizontal, and push the base to slowly bring the motorized grinding wheel closer to the angle steel, grinding the bevel into the end face. Then rotate the fixing device 90 degrees to bring the other side of the angle steel horizontal, and similarly push the base to grind the bevel. By using the fixing device in conjunction with the sliding electric grinding wheel, the operator's labor intensity can be greatly reduced, and the bevel will be smoother and more consistent. Moreover, the rotatable fixing device can be quickly adjusted to another surface that needs beveling, improving work efficiency. The operator does not need to hold the angle grinder; they only need to push the base, greatly improving operator safety. Attached Figure Description

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] like Figure 1-5 As shown, a steel structure prefabrication processing equipment includes a worktable 1, on which a rectangular slide 2 (for...) is provided. Figure 1The direction of the central slide groove 2 is the front-to-back direction, allowing the corresponding installed base 3 to move in the front-to-back direction (the direction perpendicular to the front-to-back direction is the left-to-right direction). The base 3 is slidably connected and installed in the slide groove 2. The first motor 4 is connected and installed on the base 3 at a 60-degree angle to the vertical plane (if other angles of the first motor 4 are required, simply replace the mounting plate on the base 3 that fixes the first motor 4 at different angles). The first motor 4 drives and connects to a grinding wheel 5 that can grind steel. A bearing seat 6 is also connected and installed on the worktable 1. A fixing device 7 that can clamp and fix the angle steel is rotatably connected and installed on the bearing seat 6. The bearing seat 6 has a bearing that can limit the left and right movement of the fixing device 7. The fixing device 7 can fix the angle steel circumferentially, allowing the angle steel to move left and right in the direction of the grinding wheel 5 and then be fixed for grinding. The bearing seat 6 is also provided with a stop that can limit the movement, so that the fixing device 7 can only rotate 90 degrees.

[0024] In use, the angle steel is placed into the fixing device 7, extending beyond the required bevel length. One side of the angle steel is kept horizontal, while the other side is vertically positioned downwards, allowing the grinding wheel 5 to grind the outer edge of the angle steel end face. The first motor 4 is started to rotate the grinding wheel 5. The operator pushes the base 3 along the slide groove 2 in the back-and-forth direction, causing the grinding wheel 5 to slowly approach the angle steel, grinding the outer edge of one end face of the angle steel into a bevel. Then, the fixing device 7 is rotated 90 degrees to bring the other side of the angle steel into a horizontal position, and the base 3 is pushed to grind the bevel in the same way. By using the fixing device 7 in conjunction with the reciprocating grinding wheel 5, the operator's labor intensity can be greatly reduced, and the bevel can be made smoother and more uniform. Moreover, the rotatable fixing device 7 can be quickly adjusted to another surface that needs bevel grinding, improving work efficiency. The operator does not need to hold the angle grinder to grind the bevel; they only need to push the base 3 to grind. Furthermore, by rotating the fixing device 7 90 degrees, the other side can be ground, greatly improving operator safety and production efficiency.

[0025] The fixing device 7 includes a roller 8 rotatably connected to a bearing seat 6. The roller 8 is provided with a positioning block 9 and a partition 10. The two sides of the partition 10 are a placement groove 11 and an air storage groove 12, respectively. The partition 10 is provided with a plurality of first through holes 13. A pressure plate 14 is slidably nested and installed in the first through holes 13. An air bladder 15 capable of being inflated and deflated is provided inside the air storage groove 12. The angle steel can be passed through the placement groove 11, so that the angle steel extends to the required grinding length. Then, the air bag 15 is inflated. The inflated air bag 15 will press down on the pressure plate 14, so that the pressure plate 14 slides along the first through hole 13 towards the angle steel and presses down on the angle steel. The positioning block 9 can limit and clamp the angle steel, so that the angle steel is fixed in the same position, improving the consistency of the bevel grinding by the grinding wheel 5. The air bag 15 can provide a strong clamping force after inflation. The pressure block 14 is connected to a spring that can reset after the air bag 15 is deflated. In this way, the pressure block 14 can re-exit the clamping, leaving space for the placement of the angle steel and making it more convenient for the continuous processing of the angle steel bevel.

[0026] It should be noted that the airbag 15 uses the same valve for both inflation and deflation, and it is located on the surface of the roller 8. When using it, you only need to hold the inflation gun nozzle to inject gas. Because the internal gas space is small, the inflation and deflation speed is very fast.

[0027] The base 3 includes a guide groove 16 perpendicular to the slide groove 2 and a sliding seat 17 connected to and installed with a first motor 4. The bottom of the sliding seat 17 is provided with a first threaded connecting plate 18 that can slide in the guide groove 16. The bottom of the guide groove 16 is provided with a through second through hole 181. One end of the second through hole 181 is connected to and installed with a second motor 19. The second motor 19 drives and connects to a first screw 20 that is threadedly connected to the first threaded connecting plate 18. The first screw 20 has no threads at both ends and can rotate in the second through hole 181. The other end of the first screw 20 is rotatably connected to the second through hole 181 on the side wall of the base 3. When processing thicker angle steel bevels, multiple grinding operations are required. The second motor 19 drives the first screw 20 to rotate, causing the first threaded connecting plate 18 to slide left and right within the guide groove 16. This drives the grinding wheel 5 to continuously feed into the angle steel. Through multiple back-and-forth grinding operations, the desired bevel can be obtained. This eliminates the need to adjust the protrusion length of the angle steel for grinding, improving production efficiency. Furthermore, since the diameter of the grinding wheel 5 decreases with grinding time, adjusting the distance between the grinding wheel 5 and the angle steel for continued grinding reduces the frequency of grinding wheel 5 replacement, increases the utilization rate of the grinding wheel 5, and lowers production costs.

[0028] It should be noted that the required feed distance of the sliding seat 17 is relatively short, so the sliding seat 17 can cover the guide groove 16, which can prevent dust from entering the first screw 20 and affecting the normal operation of the first screw 20.

[0029] The roller 8 has a spiral groove 21 with a helical angle of 90 degrees on its surface. The starting and ending points of the spiral groove 21 correspond to the horizontal positions of the two sides of the angle steel being clamped. A fixed box 22 is connected and installed on the worktable 1. A third motor 23 is connected and installed at one end of the fixed box 22. The third motor 23 drives a second screw 24 that is rotatably connected inside the fixed box 22. A second threaded connecting plate 25 that is threadedly connected to the second screw 24 is slidably nested inside the fixed box 22. A guide post 251 that slides in the spiral groove 21 is connected and installed on the second threaded connecting plate 25. The guide post 251 slides in a rectangular hole on the side wall of the fixed box 22. The third motor 23 drives the second screw 24 to rotate, causing the second threaded connecting plate 25 to slide left and right inside the fixed box 22. The threaded connecting plate 25 causes the guide post 251 to slide left and right in the spiral groove 21. When the guide post 251 slides to the two ends, the two sides of the angle steel are in a horizontal state, allowing the grinding wheel 5 to perform beveling.

[0030] It should be noted that, in order to prevent dust and debris from entering the interior through the rectangular opening on the side wall of the fixing box 22 and affecting the normal fit between the second threaded rod 24 and the second threaded connecting plate 25, fine brushes symmetrically arranged on the rectangular opening are required to block the entry of dust. The guide post 251 can slide freely between the brushes, or the roller 8 and the fixing box 22 can be covered together with a cover to prevent dust from entering, and at the same time, dust can also be prevented from entering the guide post 251 and the spiral groove 21.

[0031] A connecting block 26 is installed below the base 3, and a hydraulic rod 27, which drives the connecting block 26 to slide, is installed at the lower end of the worktable 1. The hydraulic rod 27 is connected to the hydraulic system. The extension and retraction of the hydraulic rod 27 drives the base 3 to reciprocate, making the feed speed of the grinding wheel 5 more uniform and controllable. Furthermore, it eliminates the need for manual operation, further reducing labor intensity, improving the efficiency of bevel grinding, and resulting in a more uniform and consistent bevel end face.

[0032] The workbench 1 is equipped with a baffle 28 that can position the angle steel. The baffle 28 can position the extension length of the angle steel, so when processing angle steel of the same type, it is not necessary to measure and determine the extension length of the angle steel from the fixing device each time, which greatly improves the efficiency and quality of production and processing.

[0033] It should be noted that a transparent dust-collecting sealing cover is also installed at the grinding wheel 5 and the angle steel grinding area. The dust-collecting sealing cover has a groove that allows the output shaft of the first motor 4 to move, so that most of the metal chips that fly out during grinding can be sealed and fall down through the holes on the worktable 1 for collection. This can reduce pollution to the working environment, block some noise, and ensure the health of the workers. The transparent sealing cover makes it convenient for the operator to observe.

[0034] This device requires regular cleaning and lubrication, including for both sliding and rotating parts. The grinding wheel 5 needs to be replaced and inspected periodically.

[0035] Both the second motor 19 and the third motor 23 are servo motors and are electrically connected to the controller. The controller can be a common PLC controller, such as the Siemens S7-200+ series. In use, the first motor 4 is started, and the angle steel is placed into the placement slot 11 of the roller 8, so that one end of the angle steel abuts against the baffle 28. The air bag 15 is inflated, so that the pressure plate 14 presses the angle steel to fix it. The third motor 23 is started to drive the second screw 24 to rotate, which in turn drives the guide post 251 to slide along the spiral groove 21, so that one side of the angle steel is in a horizontal state to be processed. The second motor 19 is started to drive the sliding seat 17 to move left and right to determine the bevel depth to be processed. For thicker angle steel, multiple processing is required. The distance of each feed needs to be set through the PLC controller. After multiple processing, the hydraulic rod 27 is started to drive the base 3 to drive the grinding wheel 5 to process the bevel of the edge of the angle steel. The cooperation of the above components improves the efficiency of beveling and reduces the labor intensity of workers. For longer and heavier angle steels, a crane can be used for hoisting and processing, which greatly improves the production efficiency of angle steel beveling, improves the processing quality of beveling, and reduces the danger to operators.
